3: Biomes
3-1: Biomes are areas on earth that have similar climates and characteristics. For example, the above picture shows a freshwater wetland biome.
3-2: This is a hot desert biome. It is characterized by a very dry climate, hot temperatures, and little cloud cover.
3-3: The above is a forest biome. It is humid, and rain falls often. It is very densely populaed with trees and the ground is coated with a layer of weeds and fallen leaves, rather than naked topsoil.
3-4: Next is a grassland biome. While it is usually humid, not much rainfall occurs. It is very sparsely populated by either plants or animals.
6: Competition: The plants here are competing for resources with, for example, the weeds growing nearby, the worms in the ground, and the grass in the background.
11: K-strategist: A K-strategy is a reproductive strategy in which the parents do not reproduce often, in order to give as many resources as possible to the offspring. The human family here has only two children, making them K-strategists, because they are choosing quality of life over quantity of offspring.
16: Organisms on different levels of the same food chain:
16-1: Grass is almost universally at the bottom of every food chain. It synthethizes its own sugars from CO2 and is prey to herbivores like …
16-2: Horses usually eat hay, which is actually dried grass stems. Where their ranges overlap, horses often fall prey to …
16-3: Venomous snakes like this one. These will bite the horse to inject venom using their fangs. However, they are not at the top of the food chain since they can be eaten by...
16-4: Crocodiles like this one. They bite and hold on to their prey using their powerful jaws. They can keep safe from the snake's deadly fangs by biting near the neck or head, avoiding either the snake's bite or rupturing the snake's venom sacs in their head.
